For the quad-core Opteron, this equates to a theoretical peak of (4 ops/clk * 4 cores * 2.5 GHz) 40 Gflop/s in 64-bit mode and 80 Gflop/s in 32-bit mode. For actual predicted performance, microprocessors use DGEMM (64-bit matrix multiply), which is typically 80 percent to 90 percent lower then the peak.

The SX240T can achieve 1.5 to 4.78 times more speed than the DGEMM speeds. DGEMM performance on a microprocessor is the best actual performance and typically hand coded in assembler by the microprocessor vendor. Typical user code that has been run through a compiler normally achieves maybe 25 percent of the peak, and even less as the number of cores increases
